LOCKING DEVICE.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed June 24, 1904. Serial No. 213,979-

To all whom it may concern:

Be it known that I, SEYMOUR W. BONSALL, a citizen of the United States, residing in the city, county, and State of New York, have invented a certain new and useful Improvement in Looking Devices, of which the following is a specification.

This invention has particular relation to means for securing wardrobe-trunks of the general type shown, for instance, in my Letters Patent No. 604,346, dated May 17, 1898, wherein the cover to be locked consists of two parts or flaps hinged at the ends of the trunk and coming together near the middle thereof. It is not to be understood, however, that this invention is limited to its application to trunks of the type "mentioned. Trunks of this type have been hitherto made with a lock at the middle of the overlapping edges of the two flaps, supplemented by spring-catches or equivalent devices at the side of the flaps to prevent springing open by bending up at the corners. This mode of attachment involves operation of at least three devices in unlocking the trunk and usually in looking it as well.

The present invention relates to an improved form of look so constructed that the middle and both sides are all simultaneously secured by one operation.

My invention is illustrated in its preferred form in the accompanying drawings, where- 1n Figure 1 is a side view of a wardrobe-trunk of the type above mentioned provided with my improved device. Fig. 2 is an elevation of a portion of the inside of the flaps when closed, and Fig. 3 is an enlarged sectional detail view of the lock-hasp on the line m of Fig. 2.

The trunk (shown at 1) is provided with a top flap 2 and a bottom flap 3, both of which are hinged to the trunk and come together at the middle. The usual guide-pins 4. are provided on the two flaps and are adapted to enter the sockets 5 and insure the proper steadying of the covers when closed. The usual hasp of the middle lock is shown at 6, and instead of being hinged to the outside of the upper flap 2, as has been commonly the practice hitherto, this hasp is rigidly fastened to a polygonal bar 7, extending entirely across the flap 2 on its inner surface. The hasp is preferably fastened by means of a tight-fitting metal strap 8, and the bar 7 turns in metal bearings 9, fastened to the inner surface of the flap 2. The material of the flap 2 is cut out sufliciently to allow the upper end of the hasp 6 to move in and out, as shown in the two positions illustrated in Figs. 1 and 3.

The bar 7 extends to a point just outside of the side valances 10, and at the two extremities of the bar 7 there are rigidly secured two hooks 11 and 12, preferably of the form shown in Fig. 3. I prefer to closely confine the sheet-metal valances 10 between the hooks 11 and 12 and appropriate sleeves or bushings 13, which are introduced between the valances and the outermost bearings 9, so as to abut upon each. By thus confining the valances they are prevented from bending, and the strength of the trunk is increased. These valances overlap the edges of the box or trunk in the usual manner.

Over each hook 11 and 12 I place a casing or guard 14., and a similar guard 15 is supplied, which is fixed to the sides of the trunk, fitting against and opposite to the guards 1 1. A pin 16 is firmly secured Within each of the guards or casings 15 and is so placed that as the hooks 1 1 and 12 revolve upward they first engage with said pins and then by virtue of their form, as illustrated, tend to embrace the same more and more closely, and thus to draw cover 2 more and morefirmlyinto place, until at last the position is reached which is shown in Fig. 3.

It will be seen that when the trunk is to be closed and the top flap 2 has been pressed substantially into place the mere closure of the hasp 6 preparatory to locking the middle lock is sufficient to operate the hooks 11 and 12, so as to firmly secure the sides and corners of the top flap 2. Since this flap overlaps the lower one, both covers are secured at once. Thus the act of locking the trunk by the middle lock also looks it at the sides and corners of the covers.

A number of changes can be made in this device without departing from the scope of my invention, and I am not to be limited to the details herein shown and described.

What I claim is 1. In a device of the class described, a cover, valances on the sides thereof, a transverse bar revolubly supported within said cover and extending outside of said valances, hooks fixed on the ends of said bar, and a lock-hasp extending through an a propriate opening in said cover and rigidly ed to said bar, substantially as described.

2. Inadevice of the class described, acover,

10 a cover therefor, catchers outside the box,

hooks pivoted outside said cover, so shaped as to draw the box and cover together as said hooks are forced onto said catches, a lockhasp on the cover and connecting means between the hasp and said hooks for operating the latter by movement of the former, substantially as described.
